The Divine establishment of knowledge

The doubt is justified by the past, not by the future. Until it is removed by knowledge, it must persist. There is a perfect knowledge at work removing the ignorance; only the ignorance is allowed to return & conquer so often, for the sake of humanity, so that its burden may be lightened. I am about to establish the parts of knowledge again, so that the faith may have some ground to stand upon.
